Hi all, i am having issues displaying ext msg features on my android phone with version 4.1.2 (API 16), it does not appear when the time is up on phone, however, it works perfectly with google chrome emulation. Can any 1 help me out in solving ext msg features not occuring in android phone? Thanks in advance!

The ext msg is suppose to work like this when the time is up, it will display a ext msg and play a sound tune on google chrome as shown in the picture below.
